Open the timer fullscreen. Set 60 seconds. Pick a calm activity from the list, like four-square breathing or window gazing. The countdown does the rest.
Two minutes of jumping jacks or animal walks. Press start, watch the countdown, return to the lesson. Total disruption: under three minutes.
Five minutes of shake-it-out, follow-the-leader, or just a stretching routine. Signals the end of one cognitive mode and the start of another.
The timer doesn't insist on choreography or animation. "Two-minute reset" framing lands. Older students appreciate a tool that doesn't try too hard.
It's really free. No paid tier, no ads, no student data sold. Supermoo is made by Reweave, Inc., a registered 501(c)(3) educational nonprofit. The work is funded by donations and grants. There is no catch.
Probably yes, since the timer doesn't require a login or collect student data. Most district privacy policies focus on tools that handle student information; a page-based countdown that runs locally typically falls below that threshold. Check your specific district's policy if you're unsure. We're happy to provide documentation if needed: support@supermoo.org.
Yes. The timer runs in any modern browser, including the Chrome browser on Chromebooks. No installation needed. It also works on iPads, Windows laptops, and Macs.
The timer keeps running. Once the page is loaded, it doesn't make further network requests. Bookmark the URL so the page is already cached.
GoNoodle is a video-based platform with a large library of guided activities, characters, and music. Supermoo's brain break timer is just a timer with a character: no video, no streaming, no login. They serve different needs. We wrote a neutral guide on choosing between brain break tools that covers this in more depth.
Please do. Send the link, post it in your faculty Slack, share it in district resource lists. The more classrooms use it, the more the work makes sense.
We have separate guides for each: indoor recess ideas for 15 to 30 minute activities when the weather kills outdoor play, brain breaks for kids with ADHD sorted by sensory type, and movement breaks for kids at home for parents (homework, screen time, before bed).
We have those too: back-to-school movement for the transition from summer, screen time and movement for breaks during long screen sessions, and wind-down activities for the evening for the hour before bed. All parent-facing, all gentle.
Teachers sit more than they realize, especially after the bell rings (grading, prep, parent emails). Supermoo's main app helps you stand up too. iPhone, Mac, Android, Apple Watch.
